Genetic Mutation

What is a gene

• a section of DNA that codes for a trait

• a pair of pants that are made of denim

• the whole entire chromosome found in the nucleus

A substitution mutation occurs when

• a base pair is missing from the DNA strand

• a base pair is added to the DNA strand

• a base pair is replaced with a different base pair

An insertion/additon mutation occurs when

• a base pair is missing from the DNA strand

• a base pair is added to the DNA strand

• a base pair is replaced with a different base pair

A deletion mutation occurs when

• a base pair is missing from the DNA strand

• a base pair is added to the DNA strand

• a base pair is replaced with a different base pair
